I guess that the Braeburn 6100 cannot be used as a zone 1 thermostat (no seperate "O" "B"), but I could still use it to program my zone 2 heating/cooling. Correct?

I thought I read somewhere the thermostat "C" terminal can be used for the "B" wire and then the "O/B" terminal can be used for the "O" wire in Zone 1. Anyone know if this is true?
